Reverse Bungee Artemis Wound

Artemis, a novelist, lost her entire family in a plane crash. Following editor Helen's suggestion, I moved to Spring and Winter City. Within a few days, and I was unfamiliar with the place, I received a strange black letter. The Black Letter claims that there is a supernatural soul exchange, and Artemis can bring her family back to life as long as she gambles on her soul. Artemis felt that what the black letter promised was too absurd, and reason told her that she should not believe in such illusory things. But the broken longing for her family made her take a chance on Heixin's promise and wanted to try it.
